IMPROVEMENT l-N FLOUR-SACKS.

Specification forming part of Letters Patent No. 51,722, dated December 26, 1865.

To all whom it may concern:

Be it known that I, J. M. HURD, of Auburn in the county of Cayuga, in the State of New.

York, have invented a new and Improved Flour-Sack; and I do hereby declare that the following is 'a'full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of referencemarkedthereon. a

In viewot the high price "of cotton cloth, paper has now been very generally substituted therefor in the manufacture of flours'acks; but as this article is to a very highdegree non-elastic, there has been found aserionsdifficulty in bringing it into such shape as to make it properly answer thepurposc" requiredtheret'or. This (lifliculty exists chiefly in forming the bottom of the sack.

In Figure 5 will be seen a sak'filled, and it will he noticed that the corners at the bottom project from the body of the sack a distance nearly equal to one-third its diameter. Now, the object of this invention is to remove this objection to the paper sack.

To enable others skilled .in the art to make and use my invention,.[ will proceed to'describe its construction and operation.

Fig. 1 is the forni into which the paper-is out before the same is folded. Fig. 2 shows the first step in the-process of making the commonsack with the piece A folded over. r Fig. 3 shows the second step, which is tofo'ld over the piece B and to paste its edge onto the'edge of the piece A. Fig. 4 showsthe third step,

which-is top-aste the piece G and to fold the;

se ne over and onto the pieces A' and B,- and shows this -common sack tille d, and as the lower corners project so very 'far from the body of the'sack, they are not only very much in the way, but are verylikely'to be ruptured and the flour lost. Fig. 6 is a. stand, and on the top} contains an apparatus, to be'described hereinafter', showing the manner of operating the invention. Fig. 7 is a representation of one of iny improved sacks before the same isfilled.

' Having-"above deseri Fig. 8 is a perspective elevation of my iniproved sack filled.

Now, it will be seen that the invention consists in so folding the paper as to entirely over eome the objectionable features above mentioned. I

Fig. 6 represents a stand, -D, set in a table,

E. On'thevtop of th'e'stand D are two leaves, F'and-G. Said leaves are hinged together and the hinges secured tothe stand D. Projecting -fr'ornthe stand I) are two pieces, H I. After the sack is-made in the common way, as represented in Fig. 4, it is opened and drawuover.

the top of the stand I), the bottom of the sack resting on the two leaves F and G. The sack, I

when drawn over as above mentioned, is represented by dotted lines, the corners terminating at'J KL M. While the bottom of the sack is resting on the two leaves above mentioned, the

triangle-piece shown in dotted lines K O P and the triangle-piece on the opposite edge, represented between the-letters Ii Q 1t, are

pasted 'and folded over onto the bottom and made to occupy-the space shown in dotted lines between the letters 0 P S and R Q '1, be-
